I am confused?!? (VERY basic question)

Hi anyone and EVERYONE,
I need help in understanding (a lot of things about dhtml) but mainly this particular small chunk of code:

if(!document.all&&!document.getElementById)
return

if (!document.all&&document.getElementById)
ns6_index=1

is the first condition asking if it is a browser that does NOT support the dom at all...
and is the second condition asking if it is NOT IE and is NN6???
And what is the index of ns_6 actually doing (is it something to do with that text node that NN6 adds to the elements)???
THANK YOU!,
Mara
